Runway Wall

Named for the airport runway it faces, this stretch of New Providence's southern wall rolls over at about fifteen meters and keeps going into the Tongue of the Ocean's abyss. The face is cut with sand chutes and crevices holding lobsters and channel clinging crabs, black coral bushes appear surprisingly shallow, and the blue beyond produces reef sharks on almost every dive, with the occasional eagle ray tracking the edge. It is Nassau's honest wilderness counterpart to the arranged shark arenas, and dawn dives here, before the day boats arrive, are the island at its best.

您此行的高光时刻: True abyssal wall minutes from shore, unbaited shark traffic

地形地貌: Coral-crusted wall dropping into the Tongue of the Ocean

水流: Gentle drift along the lip on most days.

危险因素: Bottomless wall; monitor depth constantly and keep the reef in sight in blue water.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
